Embodiment Construction

[0028] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0029] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

Abstract

The invention discloses a resonance suppression device used for a banknote code printing machine. The device comprises a wall plate and side wall plates parallel to the wall plate; a first roller shaft head and a second roller shaft head which are parallel are arranged between the wall plate and the side wall plates, the first roller shaft head is sleeved with a pressing roller, the second rollershaft head is sleeved with multiple lower number rollers, each lower number roller is provided with a fluorescent printing plate clamping ring, the two ends of the second roller shaft head are each sleeved with a vibration-prevention clamping ring, the fluorescent printing plate clamping rings are located between the two vibration-prevention clamping rings, the radius of the vibration-prevention clamping rings is equal to that of the fluorescent printing plate clamping rings, and the face, making contact with the pressing roller, of the vibration-prevention clamping rings is of an arc structure. The problems of fluorescent blackening and breezing during fluorescent printing can be solved, production efficiency is improved, and cost is reduced; and the invention further discloses the banknote code printing machine adopting the resonance suppression device.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a resonance suppressing device for a banknote printing code machine and a banknote printing code machine. Background technique [0002] In the banknote printing process, there is a need to print fluorescent codes. For example, for RMB with a face value of 50 yuan and 100 yuan, it is necessary to use a printing machine to print colorless fluorescent "50" and "100" on the lower number cylinder. When printing this kind of fluorescent code, there is a technical problem, that is, the colorless fluorescent "50", "100" and other words printed by the lower number cylinder will appear irregular fluorescent black bars, and the ink color will be faint. There will also be changes, and with the increase of the machine speed, the light bar phenomenon will intensify. In order to improve the fluorescent brightness value of the local light area, the machine personnel can only increase the amount...
